Specification of Letters Patent.

Application led April 1, 1912. Serial No. 687,686.

To all 'whom 'it may conce/m Be it known that I, Geenen A. TURNER, acitizen of the lUnited States, residing at Kane, in the county oliMcKean and State of Pennsylvania, have invented certain new and usefullmlnovements in lVoodwoi-king- Machines; and l do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to 4which it appertains tomake and use the same.

My invention relates to machines for reaching brush handle blanks, theobject being to provide means whereby the entire operation of setting,clamping, cut-ting and releasing the blanks will be automatic, and itconsists in means for automatically moving the blanks into positionagainst a solid support moving toward the cutters, means for clampingthem against said supports, cutters 'for reaching or reducing thethickness of the shank and part of the head of l the handle and meansfor releasing the blanks.

My invention further consists in the parts and combinations of parts andin the details of construction as will be more fully explained andpointed out in the claims.

In the accompanying drawings, Figure 1 is a View in plan of theimprovement; Fig. 1EL is a View of the blank before it has been operatedupon, and Fig. 1b is a view showing the blank after it has passedthrough the machine; Fig. 2 is a plan view of the revolving table withsome of the parts removed, showing the fixed table and some other partsin dotted lines. Fig. 3 is a section on line y-y of Fig. 1; Fig. 4 is aview on the line .Q2-m of Fig. 2; Fig. 5 a view in detail showing themeans for holding the table` against any vibration While the blank isbeing acted upon; Fig. 6 is a view of the mechanism for shifting theblank to position to be clamped; Fig. 7 is a view of the mechanism forantomatically dislodging the blanks after they have been operated upon;Figs. S and 9 are viewsin perspective of parts of the clampingmechanism.

1 represents a circular cured to the upper end of a vertical shaft 2,which has bearings in the supportlng frame 3. This shaft is providednear 1ts lower end with the worm Wheel 4, lmeshing with the worm 5, onshaft 6, the latter being driven by a motor, or by any other suitabletable, centrally semeans. 'lhe table is fiat on top, and is providedwith a series of radially disposed oblong openings 7, the shape ot'which is clearly shown in Figs. 1 and 2. These openings are preferablyspaced equal distances apart, and each has two straight parallel sides8, extending from a point adjacent the hub or center of the table,outwardly toward its periphery, and two straight outwardly divergentsides 8 and S" which are continuations ot the sides S, the sides 8",each being cut away at its outer end to receive one end of the head 9 ofthe handle blank 9. This cut away portion of the side wall Sl of theopenings7 conforms to the angle of one end 9 of the head of' handleblank 9, and sup orts the latter in the movement ot' the blan towardthecutters, the handle or stem 9b of the blank being supported againstthe straight wall 8b, as clearly shown to the left of the center in Fig.1.

Secured within recessed seats 10 at the outer ends of the openings 7,are the clamping blocks 11, which latter are secured in place by anysuitable means, and which have roughened or toothed faces to engage thehead end of the' blank as clearly shown in Fig. 3.

Adjustably secured to frame 3, and located under the rotating table 1,is the fixed4 table 12 which latter is arc-shaped as shown, and extendsless than halt1 way around the rotating table. Thisl table is locatedimmediately under the openings 7, and well up to the rotating table l,and forms a bottom or closure for a series of openings 7 just in advanceof the rotating cutting tools 13.

Mounted at the inner ends of openings 7 and between the parallel sides 8thereof are the clamping members 14 and 15, shown detached in Figs. 8and 9. These members rest on the flanges 1G integral with table 1, andare held in place by the removable plates 17, secured to the top of thetable, and overlapping the guide flanges of said clamping members.Clamping member 14 is simply a block with two guide flanges 14, and isprovided at its inner end with an adjustment screw 14, which may belocked against movement by set screw 14. Clamping member 15 is similarlyshaped in cross section and is provided at its outer end with a clampingjaw 15 and on top with a pin 15 against which the spring 16 bears andtends to push clampmg member 15 inwardly Patented July 8, 1913.

toward clamping member 14, the -two mem bers being ranged in pairs, onepair for each shaft 20,

and o-n opposite sides of thecam, and hold the shafts vertically andalso laterally. Each shaft is provided at its upper" handle 20a, and atits lower end with al dou-- of lever 20b ble armed leverV 201, one armof which is adapted to engage the stop 23 and turn shaft 20 in adirection -to force `its cam 19 against the head of screw 14", and thusforce both clamping members 14 and 15 toward the blank 9, for clampingthe latter in its propel position.

Each opening 7 is provided with clamping mechanism asv above` described,andeach clamping mechanism is adapted Ito receive and hold a blank Whilethe latter passes between the cutters.

The blanks are placed on table 12, one within each opening in table 1.As table 1 revolves and table 12 is stationary, the tendency is, ofcourse, to carry the blanks against the rear walls of the opening 7. Asthey move toward the cutters 13, they pass under the presser bar 24,sho-wn in detail 'in Fig. 6. This bar is provided with a rounded nose,on the end toward which the blanks,

are approaching and is considerably longer than the width of the blank.It 1s carried pass loosely,v

by twol rods 24a which latterthrough the frame 24", which, as Shown inFig. 3 is adjustably secured to table 12, by bracket 24C., and is ofcourse verticallyadsaid table 12. 'Frame 24" also carries a series ofwires or equivalent devices 24d, the lower ends of as to engage thesides of the handle blank, and force it solidly over against the rear`Wall ofopening 7, 4while thev pres'ser bar 24 forces the handle blankonto 'the table 12, iii

`the event it should happen to vbe misplaced.

J ust before'the blanks pass over, or fron ,the end ofv table 12adjacent the cutters, an

after they have been 'acted upon by the presser bar 24 and wires 24d,shaft 20 is partly turned by the engagement of one arm with stop 23.This part rotation of the shaft carries the clamp j members `14*15toward the end of the shank of the blank and firmly clamps samebetween'jaws 11 and 15a. The blank is slightly thicker thanthe'thickness of table .1, and table 12 is, so located with reference totable 1, that the blank will project equally above and below table `1.

The blank thus placed and These plates are arend with av which are solocated 20h sh release the clamping jaws, partly iinihed blank to fallcle placed under tablel 1.

In the event the blanks should stick to one or both of the jaws, afterthe pressure against theclamping jawhas been removed, I have provided anejector which consists of an arm 25 pivoted to a support 26 and providedatitsfree end with a fingerl 27, adapted as the table 1 is rotated, todrop iand disft20rand. turns cam 19 in adirecti'on to and permit theinto a receptaengages v table 1 as the latter rotates and mitting thearm 25 to fallv and car-ry its finger 27 intocontact with. the blank. In

contact with the side Walls of'openings l7, it is pivoted to arm 25 andis yieldingly held in position by spring 27a. With this machine it issimply necessary for an attendant to feed the blanks 9 onto table 12,through the` opening 7 in table 1, after which the lentire o erationisautomatic.

.In or er to prevent the table from vibrating orwabbling, I support thesame and below, adjacent the cutters, by the guides 27 b., These guidesare curved, as shown in Fig. s eachy is supported adjacent its ends bythe rods 28 mounted in bearings in bracket 29. These rods 28 areprovided with collars28t which hold them against vertical movement andeach has a threaded connection with one end of a guide, so asto permitthe latter to bel accurately adjusted up or down to com pensate for wearand also to be adjusted for tables of different thicknesses. f

By means of the handles 20a/on shafts 20, the latter can be turned byhand at any time` to cause the movable clamping jaw-to disen,-
